PROPELLER.

Specification of Letters Patent. Patented June 21, 1910,.

Application filed October 18, 1909. Serial No.- 523,273.

To all whom it may concern:

Be it known that I, ELLIOTT E. FURNEY, a citizen of the United States ofAmerica, residing in the city of St. Louis and State of Missouri, haveinvented certain new and useful Improvements in Propellers, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawing, forming part of this specification.

My invention relates to a propeller more particularly intended for usein airships, or which may be used upon other craft, such, for instance,as marine vessels. Inasmuch, however, as the propeller is especiallyadaptable for use in airships, it will be herc in Considered as utilizedupon a vehicle of this nature.v

The object of my invention is'to produce a propeller in the use ofwhich. a partial vacuum may be created in fiont of the. propeller due tothe production of centrifugal force within the propeller, thereby reducing atmospheric resistance in front of the propeller; and, further toprovide moans within the propeller housing against which the fluid isdelivered tangentially to be de fiected therefrom in a backwarddirection,

and in the striking of which thetluid acts to create force in. a forwarddirection by v virtue of which the propeller is advanced into thepartial vacuum constantly main I tained in front of the propeller.

Figure I is a front elevation of my propeller with the propeller framein section on line" I-I, Fig. II. Fig. II is a view of the propellerpartly in side elevation and partly in section,

In the accompanying drawings: 1 designates the housingof my propellerwhich is open from end to end, and is-preferably of cylindrical shape.This housing is supported by a: frame 2, preferably of rectumgularshape, as shown-in Fig. II, and which may be connected in any suitablemanner to I I mounted in e journalfboxes '3, and which may be driven by'any "suitable motor lo-' cated back of the -5 designates the hub of thepropeller ing at an angle to the plane of the body ofthe wing, and whichis adapted to cause each. wing to catch the air more efficiently duringthe rotation, of the propeller wheel.

disk 8 that serves to prevent the passage of air through the propellerwhecl throughout the radius of said disk, and which, by its presence,makes it necessary that the air acted upon by the propeller wheel withinthe housing -1 be thrown outwardly with centrifugal force to strike,tai'igentially, vanes to be next particularly mentioned.

9 designates a plurality of turbinate vanes arranged obliquely iu thehousing 1, relative to the axis-of the propeller, which are preferablyof less width at the forward end of the propeller than they are attherear end "of the propeller.

in back of the disk 8 at the rear of the pro peller wheel, whileatmospheric airpressure exerts a forward pressure against the disk,thereby affording additional propelling force,-under the influence ofwhich-the propeller is driven intothepartial vacuum constantly createdin front of thepropeller.

It is to be'n'oted that the disk 8 in m'y propelleris capableofafi'ording shelter for the motor by which the propeller-shaft l is op'erated, and which isintended to be attached directly to the propellershaft, in order that the'motor may not offer resistance even duringthemost rapid flight of an airship At'the rear of the propeller wheel isa During the rotation of the propeller or 'What may properly be termeddeflecting vanes, counteracts the tendency of the motor to rotate anairship, equipped with 111 propeller, in a; direction the reverse of t.at in which the propeller is being operated. The construction,therefore, permits the use of a. single propeller instead of twopropellers that are designed to balance each other with the object inView of preventing the rotation referred to.

' I claim:

1. In a ropeller, e, l'iousing, vanes at the interior 0? said housing,and. a propeller Wheel operable to produce centrifugal force in. said.housing and by which fluid is'delivcred ton entially therefrol'n to therear sides of sai vanes, the said propeller Wheel havinlg o disk back-ofits wi' gs.

e propeller, a. housing turbinetevanes within said housing, and apropeller operable to produce centrifugal force in said housing todeliver fluid tangentially there: from to the rear sides of saidturbinate vanes, the pro eller wheel having a disk located back 0'v itsWings.

3. In a propeller, a housing, turbinate tober 1909.
